Title: Piston type valve
Inventor: YANASE KEIICHI
IPC: F16K3/26
Filed: 1987-01-14
Abstract: PURPOSE:To prevent fine foreign matter in passing fluid from entering into a space between a valve element and the circumferential wall of a storage chamber and into the latter so that the foreign matter is accumulated, by providing a communication passage communication between the valve opening side valve element storage chamber and the valve closing side valve element storage chamber of a piston type valve. CONSTITUTION:A valve housing 1 having a passage F is formed therein with a valve closing side valve element storage chamber A and a valve closing side valve element storage chamber B which are orthogonal to the passage F. A piston type valve element 2 adapted to slide right and left in the valve element storage chambers A, B, for communicating and shutting off between a communication hole (f) and the passage F, is formed therein with a communication passage 7 for communicating between the valve opening side valve element storage chamber A and the valve closing side valve element storage chamber B. Thereby, when the valve is opened and closed, the fluid in the valve element storage chambers A, B flows only through the communication passage 7, and there is no flow between the valve storage chambers A, B and the passage F. Accordingly, fine foreign matter in the passing fluid does not into the valve element storage chambers A, B, and is therefore not accumulated, thereby it is possible to prevent the erroneous operation of the valve.

Title: Roaster
Inventor: FUKUDA NORISUKE
IPC: F24C7/08
Filed: 1986-01-16
Abstract: PURPOSE:To appropriately set the roasting degree by providing conductivity detection means for detecting the conductivity on the surface portion of a food to be roasted and determining that said conductivity has been lowered to a value lower than a predetermined value and a timer started by an output of said conductivity detection means for controlling the roasting time of the food to be roasted. CONSTITUTION:When a voltage divided by a resistor between electrodes 5a and 5b and a stationary resistor 21 exceeds a reference voltage, the output of a comparator 22 is inverted, and it is determined that the conductivity on the surface of a food to be roasted is lowered to a value less than a predetermined value. The output of a conductivity detection circuit 12 is inputted to a timer starting circuit 13 and a timer 14 is started at a point in time of the inversion of the output, that is, a point in time where the conductivity on the surface of the food to be roasted is lowered to less than a predetermined value. In the timer 14, a time (limit time) from a point in time where the food begins to scorch to a point in time where the food is roasted to a desired roasting degree is preset by the user. When this time has passed, a signal is sent from the timer 14 to a heater control circuit 15.

Title: Manufacture of semiconductor device
Inventor: MIYAZAWA YOSHIHIRO
IPC: H01L21/316
Filed: 1990-01-17
Abstract: PURPOSE:To eliminate possibility that crystallinity of the surface of a single crystal semiconductor layer is damaged, and improve shape controllability and reliability, by performing patterning utilizing oxidation rate difference between the single crystal semiconductor layer and a semiconductor oxide film. CONSTITUTION:When a silicon oxide film 2 is formed on a silicon substrate 1, and said film 2 is formed in a specified pattern, the silicon substrate 1 exposed in a region B except a region A. When the whole surface is thermally oxidized, a silicon oxide film 3 is formed on the silicon substrate 1 surface in the region B. Since the oxidation on the substrate 1 surface progresses faster in the region B than the region A, the silicon substrate 1 surface is more deeply oxidized in the region B than the region A. As a result, a step-difference (d) is generated on the silicon substrate 1 surface. Hence the region B of the silicon substrate 1 surface turns to a trench having a depth (d), and the region A turns to a pattern part. Thus the silicon substrate 1 is patterned. Thereby the patterning of a single crystal semiconductor layer wherein shape controllability is excellent and crystal defect is less is enabled.

Inventor: SAITO MASANAO
IPC: H03B5/12
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To provide an oscillation circuit capable of stable oscillating operation through a wideband. SOLUTION: This circuit is provided with a Colppits-type oscillating part 11 with a capacitor C1, a feedback capacity adjusting part 12, a tank circuit 13 and a switch control part 14, and the part 12 is provided with transistors Q2 to Q5, resistors R4 to R7 and a capacitor C2. When an oscillation frequency is low, the transistors Q2 to Q5 are turned on, and the feedback capacity of the part 11 becomes what is obtained by equivalently and parallelly connecting the capacitors C1 and C2. On the other hand, when the oscillation frequency is high the transistors Q2 to Q5 are turned off and the feedback capacity of the part 11 is fixed equivalently by only the capacitor C1.  Thereby, when the oscillation frequency is low the feedback capacity is increased to execute stable oscillation operation but when the oscillation frequency is high, the feedback capacity is reduced to avoid the generation of abnormal oscillation.

Title: Laminated inductor
Inventor: IKEDA TERUYUKI
IPC: H01F17/00
Filed: 1983-01-20
Abstract: PURPOSE:To make it possible to obtain a laminated inductor which is small in size and large in inductance, by disposing a single conductor within a magnetic member such that the conductor is coiled about predetermined two points and loops of the conductor intersect with each other through the magnetic member at a position intermediate between the two points, and connecting the conductor to external electrodes. CONSTITUTION:On sheets 21 constituting a magnetic member, loops constituting a coil are formed such as to have two centers 22 and 23, thus forming a pattern in which the loops intersect each other at the center 24 of the sheets 21. The intersecting pattern is constituted by two patterns respectively formed on the sheets constituting the magnetic member composed of two layers, that is, a pattern 25 shown by the broken line and a pattern 26 shown by the solid line are formed on the respective sheets. A through hole 27 is provided such that the two patterns are connected in series. Since the thus obtained laminated inductor has closed magnetic path formed within only the two loops, it is posible to allow the chip dimensions and the coil external dimensions to be substantially equal to each other. Accordingly, it is advantageously possible to increase the magnetic path in sectional area and to obtain a large inductance with respect to a relatively small size.
